Ultrasonic sensors are cheap enough to hack into other things, like this one-way data communications module. Continue reading “Dual Sensor Echo Locator Gives High Accuracy At Low Cost” → ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

The sensor package comprises an ultrasonic distance sensor, a microcontroller running Arduino firmware, a micro-SD card for datalogging, a real-time clock for timekeeping and sleep functions, and an ...
